运动荷重对铁路无缝线路强度计算的影响

The Impact of Motional Loading on the Intensity Calculation of Seamless Railroad

本文分析了运动荷重与基础阻尼对铁路无缝线路强度计算的影响.结果表明,运动荷重使线路变形增大,并使临界温度压力降低.这一点对设计和铺设高速铁路无缝线路尤为重要.

This article analyses the effect of motional loading and basic resist-ance on the intensity calculation of seamless railroad.The result indicates that motional loading leads to railroad deformation and expansion as well as dropping of critical temperature.This is highly important to the designing and the building of seamless railroad for express train.
